The lightest particle is (1) Positron (2) Neutron (3) Proton (4) a-particle
QGP:
Your answer is Positron
Positron is the anti-particle of electron. It has the same mass as an electron, but only an opposite charge
We know that Protons and neutrons are heavier than electrons. So they cannot be answer. And an Alpha-Particle consists of 2 protons + 2 neutrons
So, answer is surely Positron

answer is (1) Positron........
@huraira said it was Neutron. I never said that
now
..
we can take help of Google
Ok wait
ok
Provide an explanation. Answer should be up to date, and complete with a quality explanation
Neutron is the answer
Do you even know what a Positron is?
Come on, a neutron is heavier than a proton. It cannot be the answer. Think of it

Hey There!!!
The answer is (1) Positron
Here's the explanation:
-> Positron is the anti-particle of electron.
This means that the Positron has the same mass as an electron, but only a positive charge (i.e. opposite charge of electron)
So, we know that Mass of Positron = Mass of Electron
-> Next, we know that A Proton is something like 1800 times heavier than an Electron. Surely, proton cannot be the answer.
-> We also know that A Neutron is slightly heavier than a Proton. Of course, Neutron also cannot be the answer.
-> An Alpha-Particle (
) is a 
nucleus .
An Alpha Particle consists of 2 protons and 2 neutrons
Clearly, An Alpha Particle is the heaviest.
Finally, we have our lightest particle: Positron
Hope it helps

[Additional Facts:
The lightest set of particles in the Universe are the Neutrinos. There are three kinds of neutrinos known: Electron-Neutrino, Muon-Neutrino, and Tau-Neutrino. Neutrinos are ghostly particles which hardly interact with anything.
The lightest particle in the Universe is the Electron-Neutrino.
Research in neutrinos have spawned quite a few noble prizes. The latest being the 2015 Nobel Prize in Physics for discovering neutrino oscillations.
There are also extremely large Neutrino-Detection Scientific Projects under construction. One of the most exciting is the DUNE [Deep Underground .Neutrino Experiment], which is expected to help us solve some of the greatest mysteries in Physics. It will be the world's largest Neutrino Experiment ever constructed!!
One of the largest detectors currently in operation is the IceCube Neutrino Detector at the South Pole in Antarctica!
